for operating the dasheriand agitatotfFig. 8 is a top plan view of the support for the ice cream freezer or churn receptacle. Fig. 9 is a view in elevation of the detachable legs of the support shown in Fig. 8. Figs. 10 and 11 are views in top plan of the agitators or blades ofthe churn, and Fig. 12 is a View for forming a support therefor, and legs l 1 are connectec at their inner terminals to aplat e 5. The-platefi is adapted to be emanates we. plate 6, when eateries dean :apart.

wardly from the base 1, by means of bolts 7 and nuts 8. 1 The inner surfaces of theplates 5 and 6 are. preferably concaved, forming a channel or socket for anend of a standard or post 9. The bolts 7 and nuts 8 clamping the plates 5 and 6 together, securely fasten .thelower terminal of the standard or post 9 to the plates, while the legs 3 and 1 form a support for the base 1 and post 9.

Connected to the upper terminal of the standard or post 9 are clamping members 10 and 11. These members are held upon the post by means of bolts 12 and nuts 13. The

clamping member 10 .is provided with a recess 14, which is preferably made are shape.

.Mounted in'the recess 14 is the lower termi nal or ear 15 of a bracket B. The surface of the terminal 15 is rounded to conform to the shape of the recess and shoulders are formed on the bracket, as at 16, for engaging shoulders 17 formed on'the clamping member 10 to limit the rotary movement of the bracket on the clamping member.

A recess 18 isformed in the bracketB in which the upper)- terminal or ear of the clamping member: 10 is received. A bolt.19

passes through the lower terminal 15 of the bracket B, and the upper terminal ofthe clamping member 10, and a wing nut'20 is screwed upon the bolt for fastening the clamping member s 10- and the bracket ,to

gether, the adjustment of the wing nut 20 regulating the angle at which the bracket may be held upon the clamping member 10.

Connected to the bracket B are upper and lower arms '21 and 22 which are spaced Connected to the upper arm 21 is a rotatable shaft 23. Collars 24 are connected to the shaft above and below the arm 21 for supporting the shaft-upon the arm. The arm 22, as may be best seen from 'Fig. 7, is provided with. an opening 25 through which the shaft 23 extends. A bevel pinion 26 is loosely mounted upon the shaft 28 and is supported upon the upper surface of the ar1n22.' A-hub, 27, connectedto the bevel pinion 26, extends through the opening 25' in a screw 29. A bevel pinion 30 is rigidly mounted upon the upperendof the shaft 23 I Specification of Letters Patent Patented Oct. 17, 1916.

the arm, 22 a nd is connected to a sleeve 28 by and is adapted tozrotate therewith. A horizontal shaft 3-1 is mounted onlthe bracket '13 and has a bevel gear 32 connected thereto.

The bevel gear 32meshes with the bevel pin M ions as 30130? sensing the manna. at

the pinions upon the rotation of the shaft 31, by means of a crank handle 33 or other suitable means.

A hub 34 is connected to the lower terminal of the shaft 23 and is provided with a square opening 35 in which is received the squared end 36 of the agitator or dasher shaft 37 The lower terminal of the dashershaft 37 is mounted in a stepped bearing.

38, and connected to the lower terminal of the shaft 37 are a plurality of vertical blades 38 which radiate from a hub 39. These blades 38 are slightly curved and at their inner terminals and on the uppersides thereof they are cut away, as at 40, for forming a bearing for a tubular shaft or member 41 which surrounds the shaft 37. The hub 39 of the blades 38 is located below the lower edge of the tubular member 41 so that an air outlet is formed between the blades and between the lower terminal of the tubular member 41 and. hub 39.

Connected to the lower terminal of the tubular member 41, are a plurality of obliquely curved blades 42. A hub 43 is connected to the upper terminal of the tubular member 41 and is provided with a reduced outer portion which has its outer surface squared, as at 44, to receive the squared inner surface 45 of the sleeve 28. The shaft 37 extends through the hub 43 and has free rotary movement therein. WVhenpower is applied to the shaft 31, rotary motion is transmitted to the vertical shaft 23 and to the sleeve 28 through the bevel pinions 30 and 26 respectively. The rotation of the shaft 23 causes the shaft 37 to be rotated, I and the rotation of the sleeve 28 causes the tubular member 41 to be rotated in an opposite direction to theshaft 37, thereby causing the blades 38 and42 to be rotated in opposite directions for producing a churning operation. .As the blades are rotated, air is sucked or drawnthrough the openings 46 located at the upper end of the tubular member 41, down through the tubular membar 41, and discharged at the lower termi= nal thereof between the blades 38 thereby aerating the cream. By locating the blades 38, and 42 in close proximity, and rotating them .in opposite directions, the whirl which is generally transmitted to the cream, causing it to be thrown out at the top of the churn or receptacle A, is eliminated, since the blades, due to their location with respect to each other, will counteract the whirl.

The curved vertical blades 38 on the shaft 37, and the obliquely curved blades 42 of the tubular member 41, rotate in opposite directions. The blades 38 will throw the cream outwardly and create a whirl in one direction, and. the blades 42 will throw the cream outwardly and upwardly and create a whirl in an opposite direction to the-whirl created by the blades 38. This action on the cream by the blades 38 and 42 causes the air to be sucked or drawn downwardly through the tubularmember 41, thereby thoroughly aerating the cream and producing a fine grade of butter in a short time. The shaft 37 and tubular member 41 can be easily separated as they are not fastened together, and when separated a brush can be inserted in the tubular member for cleaning the same, as there are no obstructions in the tubular member to interfere with the cleaning operation.

In Fig. 12 I have shown the apparatus applied to an ice cream freezer which consists of a tub 47 mounted on the base 1, and a can or tubular member 48 mounted within the tub 47 and journaled in a step bearing 49. A dasher or agitator 50 is mounted upon the shaft 37 instead of the blades 38. The shaft 37 is connected to the hub 34 in the same manner as when applied to a churn, and a cover 51 is mounted upon the can or tubular member 48. and is provided with a hub or annular bearing 52, the annular hearing 52 being provided with a squared bore to engage the squared outer surface 53 of the sleeve 28. l/Vhen the shaft 23 and sleeve 28 are rotated, the shaft 37 and dasher 50 will be rotated-in one direction, and the can or tubular member 48 will be rotated in an opposite direction. Whenit is desired to disengage the bracket Bfrom either. the ice cream freezer or churn, the wing nut 20 is rotated upon the bolt 19, sothat the frame B can be rotated. 'As the frame is swung upwardly the sleeve 28 will become disengaged from the tubular member 41 or 48, as the case may be, and the hub 34 on the vertical shaft-23 will become disengaged from the shaft 37. In this way the bracketmay be swung for .connectingit to the dasher or blades,'or disconnecting it therefrom at any time. WVhen the brackethas been swung to a position so. that it is outof engagement with the blades or dasher of the churn or freezer, the-dasher or blades may be re moved or inserted. It will be seen that the connection between the bracket and dasher or blades can be made, or the brackets separated therefrom, without the necessity of removing the bracket from its support.

-. From theforegoing it will be seen that I have. provided an apparatus which can be assembled and operated readily and the various parts ofthe churn and freezer can be. separated and thoroughly cleansed. The tubular member 41 of the churn is not provided with any obstructions which would interfere withthe thorough cleaning of the same. As the bearings become worn the bracket B can be lowered upon the post or standard 9 by means of the clamping members 10 and 11, or the bracket may be elevated for the purpose of accommodating it to the various sizes ofchurns or: freezers.
